The Abbot of Kelso (later Commendator of Kelso) was the head of the Tironensian monastic community at Kelso Abbey in the Scottish Borders. Originally, he was the Abbot of Selkirk, because from its foundation in 1113 by David, Prince of the Cumbrians (1113-1124) until it was moved to Kelso by David (then King of Scots, 1124-1153) and John, bishop of Glasgow in 1127, it was based at nearby Selkirk. In the 16th century the monastery increasingly came under secular control, and finally in 1607 it was granted as a secular lordship to its last commendator, Robert Ker of Cesford, later earl of Roxburghe.
